Abstract
A packaged kit including an openable enclosure which is sealed
in closed packaged arrangement with a set of articles compactly
retained therein in sterile condition. The package structure
further includes a flexible sheet enveloping the set within the
closed package and arranged to define a passive sterile surface on
which the articles are disposed when the package is opened. The
articles may comprise a set of medical instruments, medicants, and
the like suitable for performing a medical procedure such as a
spinal anesthesia operation. The package structure is adapted to be
delivered in a hospital pneumatic conveyor system. The package
portions are retained in the sealed closed package arrangement by a
removable tape. A label cooperates with the flexible sheet to
define a hinge between the two portions for opening the enclosure
in the manner of a book to make the articles therein accessible in
the open arrangement. The label is placed on the outside of the
package overlying the tape to further serve as a means for
indicating the maintained closed condition of the package. The
package is permeable for introduction of a sterilizing gas
thereinto in the closed package arrangement.

Description
This invention relates to package structures and in particular to
packaged kit structures.
In different medical operations including surgical operations,
spinal anesthesia operations, and the like, a number of different
articles such as medical instruments including syringes, swabs, and
the like, medicants including anesthetics, bactericides, and the
like, sterile sheets, etc., are conventionally collected by the
nurse and brought to the medical operation site at the time of the
operation. This requires that the nurse carefully check to see that
every necessary article is obtained from the storage means and
requires the maintaining of each of the articles in a separate
sterile condition. The present invention comprehends an improved
prepackaged kit of articles, such as such medical articles,
obviating the need for such individual storage, collection and
delivery. In the illustrated embodiment, a spinal anesthesia kit is
disclosed.
Thus, a principal feature of the present invention is the provision
of a new and improved package structure.
Another feature of the invention is the provision of such a package
structure comprising a packaged sterile kit.
A further feature of the invention is the provision of such a
package structure having new and improved means for maintaining the
articles of the kit in sterile condition within the closed package
structure and providing means defining a sterile area on which the
articles are retained in the opened package arrangement.
Another feature of the invention is the provision of such a package
structure wherein the articles comprise medical instruments and
medicants for performing a preselected medical activity.
Another feature of the invention is the provision of such a package
structure wherein the articles are retained on suitable trays
within the package enclosure and the enclosure is arranged to be
opened in the manner of a book whereby the articles are made
accessible in the opened arrangement.
Still another feature of the invention is the provision of such a
package structure including a flexible sheet within the enclosure
and enveloping the articles in the closed package arrangement
thereof and arranged to be extended outwardly from the enclosure in
the opened arrangement thereof to define a sterile field on which
the articles are disposed.
A further feature of the invention is the provision of such a
package structure wherein the flexible sheet is arranged for
facilitated laying out thereof in the opened arrangement of the
enclosure by means obviating contact by the user with the inner
sterile surface of the sheet whereby the sheet defines a sterile
field.
Still another feature of the invention is the provision of such a
package structure wherein the sheet defines a hinge means between
the enclosure portions whereby the enclosure portions may be opened
in the manner of a book.
A yet further feature of the invention is the provision of such a
package structure including an outer label, and tape means for
sealingly closing the juncture of the enclosure portions in the
closed package arrangement, the label further defining hinge means
for permitting the enclosure portions to be opened in the manner of
a book.
A still further feature of the invention is the provision of such a
package structure wherein the enclosure is provided with a vent
means for introduction of a sterilizing gas thereinto in the closed
package arrangement.
Another feature of the invention is the provision of such a package
structure including label means on the outside of the package
overlying the tape means whereby the label may serve as an
indicator of the maintained closed package arrangement.
A still further feature of the invention is the provision of such a
package structure wherein tray means are provided in the enclosure
for retaining the articles therein and means are provided on the
tray means and enclosure portions for releasably retaining the tray
means in the enclosure portions.
A further feature of the invention is the provision of such a
package structure adapted to be conveyed in a pneumatic tube
conveyor in the sealed closed package arrangement.
Other features and advantages of the invention will be apparent
from the following description taken in connection with the
accompanying drawing wherein:
FIG. 1 is an exploded isometric view of a packaged kit structure
embodying the invention with the package structure in the opened
arrangement;
FIG. 2 is an isometric view illustrating a first step in the
folding of the flexible sheet drape in assembling the packaged kit
structure;
FIG. 3 is an isometric view illustrating a second step in the
assembly;
FIG. 4 is an isometric view illustrating the arrangement of the
packaged kit structure in a third step of the assembly;
FIG. 5 is a fragmentary top plan view of the packaged kit structure
illustrating the arrangement of a set of articles in an accessible
position on a tray thereof with the structure in the opened
arrangement;
FIG. 6 is a fragmentary enlarged vertical section taken
substantially along the line 6--6 of FIG. 5; and
FIG. 7 is a fragmentary vertical section similar to that of FIG. 6,
but with the package kit structure in the closed arrangement.
In the exemplary embodiment of the invention as disclosed in the
drawing, a packaged kit structure generally designated 10 is shown
to comprise an enclosure generally designated 11 including a first
portion 12 and a second portion 13. A flexible sheet drape 14
includes a first inner portion 15 received in enclosure portion 12,
a second inner portion 16 received in enclosure portion 13, and an
outer portion 17. The package structure 10 further includes a pair
of trays 18 and 19, tray 18 overlying drape portion 15 in enclosure
portion 12 and tray 19 overlying drape portion 16 in enclosure
portion 13. The drape portion 17 is folded over the respective
trays 18 and 19, as illustrated in FIGS. 2 and 3, so that in the
closed arrangement of the package 10, as shown in FIG. 4, the drape
envelopes the trays and a set of articles, such as articles 20
(FIG. 5) carried on the trays. A midportion 21 of the drape 14
extends between the enclosures 12 and 13 to define a hinge means
permitting the enclosure portions 12 and 13 to be swung from an
open book type open arrangement of FIG. 3 to a closed book, closed
arrangement of FIG. 4.
In the closed package arrangement, the enclosure portions 12 and 13
are sealingly joined by a sealing tape 22 extending along the ends
and one side of the package. The interior of the closed enclosure,
generally designated 23, may be maintained sterile by the
introduction of a suitable sterilizing gas through a vent opening
24 therein. A label 26 may be provided about the enclosure 11 to
overlie the tape 22. When the tape is pulled from the enclosure in
the opening of the package, the label will be torn along one side
of the package thereby to indicate the opening of the package. The
entire package may be placed in a suitable protective bag 27 which
herein is formed of transparent plastic. The package may be
sterilized by passing ethylene oxide thereinto as by permeating the
package material.
As indicated briefly above, the articles 20 may comprise medical
articles, such as medical instruments including syringes 28a and
28b, needles 29a, 29b, 29c and 29d, swabs 30 and the like, and
medicants such as anesthetics 31a, 31b, 31c and 31d, bactericides
32 and the like, sterilized sheets 33a and 33b, etc. The articles
20 may comprise a complete set of articles necessary for a medical
procedure, and herein illustratively comprise a set of medical
articles for administering spinal anesthesia.
Conventionally, in administration of spinal anesthesia, the skin is
cleaned by rubbing prepping solution over the area about 6 inches
above and below the puncture site. The lumbar interspace for the
spinal injection is selected, and a wheal is made by the
subcutaneous injection of procaine hydrochloride (Novocain).
Additional infiltration, if desired, is made by using a 20 or 21
gauge 11/2-inch needle. A spinal needle introducer may be inserted
through the skin wheal. In normal adults, the distance from the
patient's back to the dura in the lumbar region is about 11/2 inch.
The spinal needle must be within the subarachnoid space, but not
far enough to penetrate the anterior wall of the space. Both the
introducer needle and the spinal needle are usually inserted into
the lumbar region while the patient's back is bent, with his head
forward; but it may also be done in a lateral position. The spinal
needle is passed into the introducer with the plane of its bevel
being at a right angle to the spine to prevent cutting the dura. If
the puncture is correct and complete, cerebrospinal fluid flows
freely when the stylet of the spinal needle is withdrawn.
Anesthetic solution (tetracaine/dextrose) is then injected into the
subarachnoid space at the rate of approximately 0.5 cc. per
second.
The illustrated kit comprises a kit providing all of the necessary
components for effecting such a spinal anesthesia procedure. Thus,
the kit includes the outer polyethylene tear bag 27 which acts as a
dust cover, is nonconductive, and is usually removed outside the
operating room. The sealing tape 22 is color-coded and printed to
indicate the type of kit (spinal anesthesia) and the spinal needle
gauge and length. As discussed above, the tape insures security in
that it indicates whether the kit has ever been opened. When
completely removed, it destroys the label -- further insuring the
sterility of the kit by offering a tamper-proof feature. The label
26 lists the contents of the kit with necessary precautions. Label
26 may further be provided with directions for use of the kit as
required by the Food and Drug Administration.
The enclosure 11 may be approximately 10 5/8 .times. 5 3/16 .times.
21/2. The kit is designed to fit onto the work table of the
anesthesiologist, without overlapping the table, allowing further
utilization of the work area for additional items. It will also fit
into the conventional 4 .times. 7 pneumatic tube system used in
hospitals for the transportation of materials from one division to
another. The feel, weight, and sturdiness of the kit are designed
to give the anesthesiologist the association that he feels when
working with such kits prepared by the nurse or hospital
employees.
The sheet 14 defines a sterile field 20 .times. 26 inches, and may
be formed of white, nonabsorbent, corona discharged
(nonconductive), poly-backed material, hospital folded for opening
in a sterile, aseptic manner, enclosing the interior of the kit and
is designed to lie flat after it is unfolded. Where a heavy-duty
type paper is used as a sterile field, the anesthesiologist has to
fight the paper to keep his tray unobstructed, because it has a
memory and tends to refold itself.
The kit may include two specially designed prep swabs 30 of
urethane foam, mounted on a sturdy polypropylene handle enabling
the anesthesiologist to scrub the patient's back firmly, without
the loss of solution due to spatter or leaking.
Tinted tincture of benzalkonium chloride (1:750 in 70 percent
isopropanol) is packaged in a plastic bag 32 with a pour spout for
use as a prepping solution.
A towel 33a 17 .times. 19 inches of white, poly-backed nonabsorbent
material is provided to be placed under the patient to prevent
contamination and discoloration of the operating field. A
fenestrated sheet 33b, 22 .times. 26 inches, which is green to
match the color of the operating field, is formed of gummed,
nonabsorbent material, with a 4 .times. 4 inches oval fenestration.
The sheet 33b is usually placed over the patient's back after the
area has been scrubbed. The fenestration is centered over the
interspace of the vertebra where the anesthesiologist plans on
making his puncture.
A 21/2 milliliter syringe 28a is normally used in combination with
a 25 .times. 5/8 inch needle 29a to raise a skin wheal over the
proposed puncture site. Prior to the introduction of the spinal
needle, an attempt may be made to anesthetize the area by injecting
a local anesthetic (Novocain or the equivalent) subcutaneously. A
21 .times. 11/2 inch needle 29b is used after the skin wheat has
been raised to further infiltrate the Novocain into the area of the
proposed puncture. A 2 milliliter ampul 31a of procaine
hydrochloride, 1 percent (10 mg./ml.), is used as a local
anesthetic at the puncture site. A 6 milliliter syringe 28b is used
by the anesthesiologist to mix the tetracaine hydrochloride and
dextrose for injection into the spinal canal. The specific gravity
of the cerebrospinal fluid averages about 1.005 to 1.009. Depending
upon the area where anesthesia is desired, the anesthesiologist can
adjust the location of the anesthetic agent in the spinal canal by
the addition of dextrose solution from a 3 milliliter ampul 31b of
dextrose, 10 percent (100 mg./ml.). (For example, an isobaric
solution has the same specific gravity as the cerebrospinal fluid
causing the solution to remain and produce anesthesia at the level
of injection; a hyperbaric solution has a specific gravity greater
than the cerebrospinal fluid causing it to migrate downward and
produce anesthesia below the level of injection; a hypobaric
solution has a specific gravity less than that of the spinal fluid
causing it to migrate upward and produce anesthesia above the level
of injection.) The 2 milliliter ampul 31c of tetracaine
hydrochloride, 1 percent (10 mg./ml.) is used as the primary
anesthetic agent.
An 18 gauge by 11/2 inch introducer/mixing needle 29c is provided
with a specially designed hub to enable either a 20, 22 or 25 gauge
spinal needle to pass through the cannula without burring the
spinal needle. When used as an introducer, the needle is inserted
into the puncture area before the spinal needle is introduced. Its
purpose is to minimize contamination of the spinal canal. For those
doctors who prefer not to use an introducer, the needle may be used
for drawing up and mixing of solutions from the drug ampuls.
One milliliter ampul 31d is of ephedrine sulfate (50 mg./ml.).
Ephedrine is normally used prophylactically as a vasoconstrictor to
maintain blood pressure. When desired, the ephedrine is injected
subcutaneously or intramuscularly. The spinal needle 29d may be 20,
22, or 25 gauge by 31/2 inches.
Thus, the complete set of medical articles may be prepackaged in
the package 10 by the manufacturer and maintained in a sterile
condition for long periods of time. When it is desired to use the
packaged kit structure 10, the user need merely remove the
protective bag 27, pull the tape 22 free from the enclosure while
leaving the hinge portion 34 of the label in place on the
enclosure, as shown in FIGS. 6 and 7. The enclosure portions 12 and
13 may then be swung open with the sheet portion 21 and the label
portion 34 cooperatively defining hinge means to permit the opening
of the enclosure in the manner of a book to the position of FIG. 3.
The folded ends 35 of the sheet are then unfolded to the extended
position of FIG. 2. The sheet may be folded to include a corner
fold 36 which may be grasped by the user to facilitate the further
unfolding of the sheet without contacting the inner sterile surface
thereof to extend the outer portion 17 of the sheet laterally
outwardly from the enclosure portions 12 and 13 as shown in FIG. 1.
Thus, the upper surface of the sheet portion 17 defines a sterile
field on which the trays 18 and 19 rest with the articles 20
carried by the trays fully accessible to the user.
As shown in FIG. 5, the trays may be formed with suitable recesses
37 for retaining the respective articles 20 for facilitated
utilization thereof. The trays 18 and 19 are retained in the
respective enclosure portions 12 and 13 by an interlocking rib
means 38 thereon, as shown in FIG. 6. The trays may be supported in
the respective enclosure portions by ribs 39 upstanding on the
enclosure portions. The enclosure portions 12 and 13 are similarly
provided with interlocking portions 40 along the edges thereof
which when the enclosure portions are swung to the closed package
arrangement of FIG. 4 interengage to mechanically retain the
enclosure portions in the closed package arrangement. Thus, each of
the interlocking portions 38 and 40 and the ribs 39 function to
strengthen the enclosure portions which may be formed of a
relatively thin material such as plastic.
Thus, kit structure 10 provides an improved package which may be
maintained in a sterile sealed condition while yet being readily
openable to provide access to the articles retained on the trays
therein. The sheet means provides an improved enlarged sterile
field laterally beyond the trays so that the kit may be used on
relatively unsterile surfaces while maintaining the sterility of
the articles. The kit structure 10 is extremely simple and
economical of construction. As indicated above, the enclosure may
be formed of a relatively thin plastic. Likewise, the trays may be
formed of a relatively thin plastic as the recesses 37 effectively
define reinforcing portions thereof. The sheet 14 may be formed of
a suitable flexible material. The tape 22 may comprise a pressure
adhesive tape. As the kit may be assembled by the manufacturer,
omissions in the necessary articles is effectively eliminated.
Relatively unskilled personnel may be used to provide the kits for
use in the different medical procedures, thereby minimizing
hospital and clerical expenses. The kit is adapted to be conveyed
through pneumatic tube conveyor systems employed in the newer
hospitals without damage to the articles contained therein by
virtue of the padded resilient disposition of the trays within the
enclosure.
While we have shown and described one embodiment of our invention,
it is to be understood that it is capable of many modifications.
Changes, therefore, in the construction and arrangement may be made
without departing from the spirit and scope of the invention.
